The Square D QO2401021 is a molded case circuit breaker from the QO Series, designed to provide overcurrent protection through thermal magnetic operation. This 2-pole, 40A breaker is rated for 120/240V AC, single-phase systems, with a 10kA interrupting capacity at 240V. It features a shunt trip mechanism for remote disconnection, measures 3.1 in x 2.2 in x 2.9 in (79 mm x 57 mm x 74 mm), weighs 0.92 lb, and uses a plug-in connection with lug terminals accepting AWG 8 to AWG 2 copper or aluminum wire. The unit is CSA certified and UL listed, with a temperature rating of -13°F to 158°F (-25°C to 70°C), and is compatible with QO Load Centers and NQ Panelboards. Typical industrial applications include branch circuit protection in commercial and light industrial power distribution systems.
